Plant geneticists continue to modify and refine the DNA of agricultural products, altering genes that affect the abundance and taste of the crop. Eventually, the entire genome of every major food crop will be subject to such manipulation. Once these scientists have mastered the DNA of all major food crops, no obstacles to abundant, delicious vegetables and grains will remain.The argument to the left is based on which of the following assumptions?ChoicesA All obstacles to agricultural production are susceptible to genetic remedies.B Obstacles to the agricultural production are susceptible only to genetic remedies.C There is already a visible change in produce size at supermarkets, attributable to genetic manipulation of crops.D Produce taste tests should be conducted to compare genetically modified produce and natural produce.E Consumers have grown increasingly skeptical of the merits of genetically modified produce.

A. it is.

Let's neglect the assumption that all agricultural production issues can be solved genetically.

What if some problems with major ag crops cannot be solved genetically.What if manipulation of abundance and taste are among those genetically unsolvable problems. Then we cannot be so sure that no obstacle to abundance and taste of all major crops will remain.

A

After browsing through all the choices, almost everyone narrows down to A & B. Read these two carefully, and you will realize that they have different meanings. Some ppl pointed out that "Taste" and "Abundance" can't be pointed out as ALL the obstacles. Well, taste and abundance is basically everything you need from the crops.

Assumption is not that "only" genetic remedies can solve all problems ..... nothing in there says that only genetics can solve all the problems....... however, assumption is that once we have figured out the complete genetic makeup of the crops, we will be able to solve taste and abundance issues. A is right on target. Whether taste and abundance are all the issues or there are more is a mere distraction.

When you read the argument the assumption seems to pop out is that some how there is a solution through genetic modification for all issues -- "Once these scientists have mastered the DNA of all major food crops, no obstacles to abundant, delicious vegetables and grains will remain." This is one clueThe argument to the left is based on which of the following assumptions?ChoicesA All obstacles to agricultural production are susceptible to genetic remedies. Precisely what jumped out. This is a logic gap kind of argument where choice A fills the GAP : refer to MGMAT CR Guide Assumptions chapterB Obstacles to the agricultural production are susceptible only to genetic remedies.C There is already a visible change in produce size at supermarkets, attributable to genetic manipulation of crops.D Produce taste tests should be conducted to compare genetically modified produce and natural produce.E Consumers have grown increasingly skeptical of the merits of genetically modified produce.
